What is jsesc?

The jsesc npm package is a library for escaping JavaScript strings while generating the shortest possible valid ASCII-only output. It's useful for avoiding syntax errors when embedding data in JavaScript code or for preparing data to be JSON-encoded.

What are jsesc's main functionalities?

String escaping

Escapes any occurrences of U+2028 (line separator) and U+2029 (paragraph separator) among other potentially problematic characters in JavaScript strings, making the output safe for inclusion in HTML/JavaScript templates.

"jsesc('foo \u2028 bar \u2029 baz')"

JSON escaping

Converts an object to a JSON string, ensuring that the output is safe to use in JavaScript by escaping any characters that could cause syntax errors or security issues.

"jsesc({ 'foo': 'bar' }, { 'json': true })"

ASCII-only output

Escapes non-ASCII symbols into their Unicode escape sequences to produce an ASCII-only output. This is particularly useful for minimizing encoding issues or for environments that do not fully support Unicode.

"jsesc('foo © bar ≠ baz 𝌆 qux', { 'es6': false })"
